Thanks for reading.

Hidden Weapons and Armour

Legendary Sword:

• Hawkman required
  
• A Gold Key

Once you have the ability to fly, from Monster Town fly to the far right and keep flying untill you come to the destroyed castle. Remember that locked door when you were last here? Enter it and go to the Mecha dragons room. Inside will be a chest with the Legendary Sword inside.

Legendary Armour:

• Hawkman Required
  
• Gold Key required

After you get the Legendary Sword after returning to the Mecha Dragons room, head to the escape path from the previous time you were here. For me there was a blue Cyclops who had a 100% drop rate on the armour.

Legendary Shield:

• Hawkman Required

Thanks to Zoppy Lums for info.
When you go again in the destroyed castle, in the same spot when you come out to the far right. Push 'Up' inside of the well. It's on sale for 5890 coins.

Tasmanian Sword:

• Lionman Required

In the Underground keep going to the left, The path will split into dead ends a few times. The final time will be a long split. In the upper path there will be a split between the stages, go through it. On the other side will be the dead end with a hidden door right at the end. Inside the sword can be purchased.
To use its special ability you jump into the air, hold up and hit attack. It will transform you between your forms like the changing rooms.

Gallic Sword:

• Bracelet
  
• 4charm stones.

Thanks too Zoppy Lums for info.
Once you have the charm stones return to the enterence of the underground. The room with the 3 large pipes and destroy the lone block to access the shop. Inside the Charm item will be the sword.

Hidden shops and rooms (In no special order)

Shop 1:

• Hawkman Required

In Monster town there is the platform with 4 blocks you always exit too after an escape room. If you fly up from there you will come to the underside of the Desert door, dirrectly under it press up and you will enter a hidden shop in thesky. It sells Thunder and a life potion.

Shop 2:

• Hawkman Required

From Monster Town Fly to the right over the wall and there will be a shop hidden just over it.
Contains the Heavenly Shield and a gold key.

Shop 3:

• Hawkman or Piranhaman Required
  
• Bracelet Required

There are 2 ways ot access this shop.
The first way and earlyest is on the way back to the Beach after doing the Volcanic zone.
When you are swimming through the sewers under Monster town keep an eye out for an area where the water comes close to the top of the map. If you swim up and jump you will find yourself outside a shop guarded by blocks.
The Second way is to just fly there by going Right from Monster town untill you see it. Its the second shop you see.

Hidden Room 1:

• Hawkman or Piranhaman Required

From the previous shop either Fly or jump up the blocks and continue Right. You will come to a door with a chest inside.

Hidden room 2 and 3:

• Hawkman Semi Required
  
• Bracelet Required

No so much a Hidden room as more a bonus area full of chests. When you reach the Pyramid in the Desert keep going to the left over it. You will come to a Sphinx. Inside is a room with a chest but dont those walls also look breakable? Do so.
Through the wall and down you will come to an area with 8 chests. You can open one then you need to leave by pressing up anywhere inthe room. You will be right outside. Repeate this untill all the chests are clear.
There is also a door on the very top center of the chest room which exits above the Mummy Dragons room. If you are fast as Birdman you can fly, head left for a bonus chest.

Shop 4:

• Mouseman Required

To the far left of the city just before the Forest zone is a narrow passageway only Mouseman can pass through, there are red spike ball enemies in the passages. When you enter take the path that puts you on the very top level. Go as far left as you can and jump.

More to come.

Charm stones

Hawkman Stone:

Hi guys! Am I the only one losing sleep over that single breakable block on Sky Palace after you switch to Lion Man?

[Radiant]

Hidden room 4: on the way to the temple, in the underground, you come across a disconnected / unreachable area at the bottom. Above the rightmost part of this area is a hidden door that leads there. In the left of this disconnected area is a hidden door with a chest.

You can get the third heart before defeating zombie dragon, just use mouse mode to climb the wall.

[Jhagunssu]

At the entrance to the well, if you break the stone, pick up the "?" and instead of entering the transformation room, you touch the wall and press up, you will enter a secret door inside the pyramid, next to the boss room.

Thanks for this info and the great guide! This point could maybe be worth adding into the secret weapons and armor section? It's a secret capability, even if the armor itself is not hidden.

[Sililos]

When you lose all your hearts, it refills them.

[EZ Smoke Dawg]

What is the special ability of the Hades Armour?

[Kjaer18]

Thank you for the instructions of how to use the sword to change forms. Apreciate it!
